The model is initially calibrated and validated against observed&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/onshore-wind\">onshore winds<\/a>&nbsp;at four weather stations before its main simulation for the two-years study period of 2018\u20132019. As a result, the spatially averaged annual wind speed errors between the WRF and L2 OCN data are 0.70&nbsp;m\/s for&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/mean-bias-error\">mean bias error<\/a>&nbsp;and 0.79&nbsp;m\/s for&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/root-mean-square-error\">root mean square error<\/a>, indicating good model performance. The annual mean wind speeds over the Cambodian Sea are 5.15&nbsp;m\/s, 5.20&nbsp;m\/s and 5.27&nbsp;m\/s at 80&nbsp;m, 100&nbsp;m and 140&nbsp;m above sea level, respectively. Then, analytic hierarchy process (AHP) is applied to evaluate the optimal sites for offshore&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/wind-power-generation\">wind power generation<\/a>. The most potential areas in Cambodian sea are along Kampot and Kep shoreline. The resulting AEPs are 11,949.02&nbsp;GWh for 80-m V112&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/turbine\">turbines<\/a>, 20,013.34&nbsp;GWh for 100-m V164 turbines and 31,880.48&nbsp;GWh for 150-m HX12 turbines, which could reduce CO<sub>2<\/sub>&nbsp;emissions by 5.48&nbsp;Mt-CO<sub>2<\/sub>, 9.18&nbsp;Mt-CO<sub>2<\/sub>&nbsp;and 14.63&nbsp;Mt-CO<sub>2<\/sub>&nbsp;per year, respectively. If 10% of the total AEP could be generated by 2030, the offshore wind source would contribute to 1.95%, 3.27%, or 5.20% of the country&#8217;s electric demands forecasted for 2030. The integrated assessment methodology and resources adopted in this study can be applicable to other regions particularly where offshore measurements are not readily available.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A long-term effort from Sokline and Karodine is now accepted and published in Renewable and Sustainable Energy Reviews, the No. 1 journal (IF: 14.982) in&nbsp;Green &amp; Sustainable Science &amp; Technology.
